Special Containment Procedures:SCP-1123 is to be kept electromagnetically suspended in a hermetically-sealed cubic container measuring at least one-half meter on every edge. This container will be periodically rotated between sites due to the sensitive nature of the information it provides and will be guarded by at least four (4) security personnel at all times.

As of Incident J1123-16, experimentation with SCP-1123 is impossible. SCP-1123’s container must also be expanded to 20 meters on every edge and must be composed of pure lead or other sufficiently dense metal to prevent radiation leakages. Under absolutely no circumstances shall the container be opened without express written and verbal approval from at least two (2) level 4 personnel. No radioactive material is to be allowed within 50 meters of the containment area. Any and all communication attempts by either SCP-1123 or SCP-1123-2 must be reported immediately to level 4 personnel to be relayed to O-5 command. Should SCP-1123-1 reemerge, the entire facility must be immediately evacuated and O-5 command directly notified. Rotation of container is no longer necessary.

Description: SCP-1123 was originally discovered by a precursor to the Foundation in Siberia in 18██ encased in a block of ice. How its location was discovered remains unknown. It was transferred into Foundation custody in 19██ at which point its properties became known.

SCP-1123 is a cylindrical tube measuring 30 cm in length and fifteen 15 cm in diameter. Although appearing metallic, sample collection has proven impossible due to the item’s unusual properties, as follows. SCP-1123 emits a mild form of radiation similar to that of SCP-119, which intensifies the closer it is to the object. This radiation appears to effectively “speed up” the time around it while also dampening the effects of gravity. Although its effects are negligible beyond 15 cm around the object, the intensification of its effects causes any object coming close to making contact with it to instantaneously vaporize. Analysis of the particles given off by such a reaction indicates that each individual particle approaching contact with the object underwent rapid radioactive decay even if its half-life was billions of years. Testing with metals denser than lead has been expressly forbidden due to the possibility of a massive pulse of high-energy radiation if near-contact is made.

Initially, the object was unremarkable apart from these properties and remained in containment for several decades without incident. On ██- ██- 20██, however, its additional anomalies were discovered (See Experiment Log 1123-I). Based on those events, SCP-1123 was apparently in a “dormant” state and was “activated” by contact with human blood, at which point it displayed the capacity for speech in a disembodied voice.

It is currently unknown how it was able to “calibrate” its language, and investigation into any telepathic properties has proven inconclusive. Further communication outside of the experiment logs when SCP-1123-1 was not being generated has resulted in the following information:

SCP-1123 appears to have "quirks" in its language, often inserting the words PAUSE or WORKING when it is doing one of those in the middle of a conversation. This is theorized to be because it was programmed to interpret more "enlightened" languages, causing it to have to "work" to find the English word closest to what it wished to convey when no word actually fits or in similar instances.

It appears that when SCP-1123 prefaces something with "PROGRAMMED RESPONSE:" it indicates that a preset phrase has been inserted into its system to be repeated whenever certain questions are asked. When inquired as to what "PROGRAMMED RESPONSE:" meant, SCP-1123 replied that it does not remember ever saying anything like that, saying that it actually answered the question to the best of its abilities.

There also seems to be certain things which SCP-1123 does not comprehend ignorance of, such as not understanding what "The Entity" it refers to is. After being asked several times to explain it, SCP-1123 displayed an inordinate amount of insight by analogizing explanation of "The Entity" in English to attempting to convey the color blue to a blind person.

Most remarkably, SCP-1123 has indicated its purpose to be the tracking and observation of what it calls “the entity,” hereafter referred to as SCP-1123-2. It has displayed the ability for “manual observation of the entity”, creating a space-time anomaly (SCP-1123-1) that leads directly into what is believe to be various locations in the interior of SCP-1123-2. Exploration through SCP-1123-1 has shown SCP-1123-2 to be of immeasurable proportions, with preliminary surveys of its gravitational pull being similar to that of Jupiter. “The entity” also appears to be mobile not only through space but also through [DATA EXPUNGED]. It is considered to be highly dangerous and any possible movement that can be identified as towards Earth must be recorded and reported immediately. (See Experiment Logs 1123-II through 1123-IV)

Addendum: Following Incident J1123-16, SCP-1123’s radiation field has intensified greatly, increasing its effective radius to 18 meters and causing it to float in mid-air when not acted upon. Any and all communication attempts with SCP-1123 have also been futile. SCP-1123-2 has now displayed the capacity for communication and psychological attacks. Temporarily upgraded to Keter classification pending further consideration from O-5 command upon review of the experiment logs; see Experiment Log 1123-V.

D-119084 inadvertently cut his finger, causing blood droplets to fall onto SCP-1123. D-119084 was severely reprimanded until it was realized that the blood had actually made contact with the object, somehow penetrating the radiation.

At this point the object began to give off a faint glow and “whirring” sound as well as some sort of unintelligible screech. (Later analysis of the audio recording indicated that the frequencies were well above and below the audible region as well. It is theorized to be some sort of language by Foundation linguists) After a brief pause in the “screech,” the “whirring” sound intensified, possibly indicating the object was “working” for a period of 2 minutes. Shortly thereafter, a disembodied voice began to speak English, seemingly from every direction. The following is the audio log for the next several minutes, abridged:

SCP-1123: PAUSE. I am the personal artificial intelligence attached to this beacon.

Dr. █████: Beacon?

SCP-1123: This beacon is a WORKING… beyond ancient object designed to track the entity and to inhibit its entrance into these coordinates if necessary. I was created WORKING… much later to convey its function to [DATA EXPUNGED] and sentient races.

Dr. █████: What entity?

SCP-1123: The entity.

Dr. █████: Why track it?

SCP-1123: Danger.

Dr. █████: What kind of danger?

SCP-1123: The Danger.

Dr. █████: You are not being very helpful.

SCP-1123: PROGRAMMED RESPONSE: If you do not know, you will not understand.

Dr. █████: Who created you and the beacon?

SCP-1123: [DATA EXPUNGED]

Dr. █████: When was the beacon created?

SCP-1123: “When” does not apply to the beacon. PAUSE… I must work.

At this point SCP-1123 became unresponsive and the intense “whirring” sound returned. As an experiment report was being drawn up, SCP-1123 resumed communication:

SCP-1123: Further information on the behavior of the entity may be acquired through manual observation, although it is not advised.

Dr. █████: How does “manual observation” work?

SCP-1123: PROGRAMMED RESPONSE: If you do not know, you will not understand.

Dr. █████: Can we manually observe?

SCP-1123: MANUAL OBSERVATION INITIATED

SCP-1123 became momentarily unresponsive again as the “whirr” began to become exponentially louder, reaching a stable maximum of approximately 140dB. The room was quickly evacuated as a precaution. After approximately 2 minutes and forty 40 seconds, a 2-dimensional black oval materialized in front of SCP-1123, creating a shockwave equivalent to 5 sonic booms, cracking the reinforced concrete walls of the room. Following evaluations to ensure that the area remained structurally sound, a robotic probe was dispatched which determined that radiation levels had risen slightly. Upon inspection of the black anomaly it was discovered that objects inserted into it were transported to an unknown location upon passing through the anomaly. Attempts to reestablish contact with SCP-1123 were not successful.

Upon determining that the "portal" was stable enough, researchers agreed to take time to plan an experiment to be carried out at later.

Experiment Log 1123-II: ██- 05- 20██: Planned robotic expedition into SCP-1123-1 to determine, if possible, to where it leads and what may be observed on the other side. Overseen by Dr. █████.

Equipment: Explorer Mark IV experimental pathfinder, equipped with a long-range GPS, both a corded and wireless video transmission device (it was unknown if wireless signals could be transmitted across SCP-1123-1), and 300 Watt floodlight.

The robot was carefully lead into the "portal," and upon crossing it proceeded to enter a free-fall for approximately 30 seconds according to gyroscopic and force sensors (nothing was visible through the video feed as the floodlight failed to activate) before it reached the end of its cable which promptly snapped allowing it to resume free-falling for another 2 minutes and 30 seconds. The robot eventually collided with an unidentified solid surface at a velocity far exceeding the robot's theoretical terminal velocity on Earth, damaging several of the robot's systems, most notably locomotion. A faint blue glow with two black dots spaced shortly apart slightly above the center became visible on the highly distorted video feed, and was the only thing distinguishable even after the eventually successful activation of the floodlight. Robot continued to send data for another 2 minutes before a fatal systems error. GPS signals returned through the "portal" were nonsensical.

Upon entry into SCP-1123-1, researches were surprised to discover that the robot did not enter free-fall, but rather rested on a solid surface. The flood light was successfully activated, but video feed revealed only minute, floating dust-like particles. The camera was panned down to observe the ground and it appeared to be some sort of stiff but spongy, membranous material. A small sample was taken of the material to be examined later.

Robot guided forward away from the point of origin for approximately 30 minutes, eventually arriving at what appeared to be a giant wall extending upwards several hundred meters before disappearing into blackness. Robot re-oriented to travel to its right, parallel to the wall. Approximately 40 more minutes elapsed before researchers examining the video feed realized that the wall was somewhat noticeably curving slightly away from the robot and instructed the operator to carefully measure this curvature as he continued the exploration.

Several more hours passed uneventfully as the robot remained on the same course. Seeing that no new information was being gathered, Dr. █████ instructed the operator to shift the video feed to see in the infrared spectrum (possibly out of boredom). Upon doing so, it was noticed that traces of infrared light were being given off from within the wall. Observation seemed to indicate that some sort of fluid was moving quickly through the wall in both directions. Vision was then also shifted into the ultraviolet spectrum where massive amounts of ultraviolet radiation was seen radiating from within the wall, seemingly from the same fluid.

At this point, the Explorer's power reserves began to run low and it successfully navigated back to SCP-1123-1 and returned through it.

Data Analysis: Initial inspection of the sample gathered by the Explorer seemed to indicate that it was some sort of tissue; microscopic analysis of the sample revealed however that it appeared to be an incredibly large macro-molecule composed of predominantly Carbon, Silicon, Aluminum, and Phosphorous with significant amounts of Hydrogen, Oxygen, Zinc, and Selenium. Trace amounts of Uranium, Osmium, and Technetium were also detected. (It should be noted that every atom of Uranium found in the molecule was somehow entirely stable radioactively) Extrapolation of the molecule's structure has proven impossible due to its remarkable complexity. Having been separated from the rest of the "ground" the robot was on, it is unknown how large the original molecule would have been.

The "wall" seen during the exploration was theorized to be an extremely large cylinder upon review of the video. Geometrical analysis of the measurements taken indicated that such a cylinder would have to be approximately █████ kilometers in diameter given its curvature.

Review of the footage gathered during the navigation around the "wall" showed that a smaller version of the blue glow witnessed in the first expedition was minutely visible in varying locations throughout.

Experiment 1123-IV: ██-04-20██: Planned expedition into SCP-1123-1 with the purpose of obtaining further samples and creating, if possible, a map of the area explored through radar mapping equipment. Overseen by Dr. ███████ following Dr. █████'s incident with SCP-████.

Equipment: An Explorer Mark ██ experimental pathfinder, equipped with a powerful radar mapping system, detailed wide-spectrum light analysis, long-range wireless video feed, and enhanced locomotive capacity. An unremarkable probe was also used to test the conditions on the other side of SCP-1123-1 prior to the robot's entry.

A probe was first launched into SCP-1123-1 which was found to enter free fall immediately. After waiting a period of 5 minutes with the probe continuing to fall, the team outfitted the Explorer for flight and sent it through. Upon entry into SCP-1123-2, the radar mapping system was activated and began to record data. Analysis of the readings found that there were no detectable boundaries to the open space the Explorer was in, but they did show a large web of string-like structures that grew perceptibly thicker in front of the Explorer. Moving further towards the estimated center of the structures, they became visible in the Explorer's floodlight as brightly-colored fibrous tendrils. The explorer began to take readings that detected electromagnetic fields emanating from the fibers, but the instruments ceased functioning and the video feed suddenly went dark shortly after there was a marked spike in the electric activity, spurring a short panic to restore it.

A few moments later, researchers that were observing the video feed reported that they had strange tastes in their mouths that dissipated when they turned from the screen. After several futile attempts to restore the video were made, Dr. ███████, acting on a hypothesis, placed a printout of the feed shortly before it cut off next to the screen then asked the other researchers present to attempt to find any correlation between the color on the image and the taste they experienced when looking at different areas of the screen. It was reported that similar colors seemed to have similar tastes. One researcher reported "tasting something blue" faintly somewhere he shouldn't have, but soon said that it had disappeared. Shortly thereafter, during an argument between two members of faculty over how to best describe the "taste" of red, the video feed seemingly returned to normal but the two front and rear mounted cameras appeared to be viewing the Explorer itself. The Explorer's sensor suite immediately began to act erratically, appearing to suffer from some sort of extreme feedback loop. The audio feed was immediately cut to prevent aural injury from the screeching sound being emitted from the speakers at their maximum capacity. Before the staff could reconfigure the instruments, all the readings changed again without warning. An abridged list of the abnormalities recorded during these sudden changes is given in the data analysis.

After approximately two hours, readings returned to normal, but with all numbers being off from their expected values by a factor of Euler's number. The Explorer's operators took this opportunity to attempt to and successfully navigate the equipment back to and through SCP-1123-1.

Data Analysis: List thing goes here

Addendum: On ██-07-20██, Dr. ███████ was briefing Dr. █████ on Experiment 1123-IV and asking his opinion, particularly on the strange readings gathered during the "shifts" when SCP-1123 became vocal. Dr. █████ immediately began recording audio, which is abridged and transcribed as follows:

Dr. █████: I apologize, could you repeat what you just said?

SCP-1123: Repeating— "This beacon may be of use in explaining these phenomena."

Dr. █████: That would be very much appreciated. What can you tell us?

SCP-1123: Repeated manual observation of The Entity stimulates it to WORKING… move.

Dr. █████: How does its motion cause these strange readings?

SCP-1123: PAUSE… I do not understand how its motion would not.

[REDACTED]

Dr. █████: Is there perhaps another word that could better describe this [DATA EXPUNGED] you speak of?

SCP-1123: WORKING… Dimensionstring is the closest match.

Dr. █████: I see. So—

SCP-1123: OBSERVATION— further explanation appears impossible. This Artificial intelligence will now enter dormancy.

SCP-1123 then became non-responsive despite many further attempts to re-activate it.

Experiment 1123-V: ██-16-20██: Planned expedition into SCP-1123-1 with the purpose of obtaining further samples and creating, if possible, a map of the area explored through radar mapping equipment. Overseen by Dr. ███████ in collaboration with Dr. █████.

Equipment: An Explorer Mark ██ experimental pathfinder, equipped with a powerful radar mapping system, detailed wide-spectrum light analysis, long-range wireless video feed, and enhanced locomotive capacity. An unremarkable probe was also used to test the conditions on the other side of SCP-1123-1 prior to the robot's entry. Additionally, a component of SCP-████ was added in this trial in an attempt to determine the probe's location following entry into SCP-1123-1.

As previously, the preliminary probe entered a sustained free-fall immediately and the Explorer was outfitted for flight. The Explorer was successfully navigated into SCP-1123-1 and began to take readings. Information gathered from SCP-████ appeared meaningless. Radar mapping of the area revealed immeasurably large and indistinct masses floating in the space. Background readings of radiation resembling but distinct from that emitted by SCP-1123 were recorded.The Explorer was guided to and successfully landed on one of the masses. On-board chemical analysis of a collected sample revealed it to be composed of rock-like material (█████████), though the sample was too complex and the instruments too limited to determine its composition more accurately. Over the course of the next two hours, it was determined with the Explorer's [REDACTED] that at least three of the masses were on an approximately continental scale and were composed of similar materials. While measurements were being conducted on a fourth mass, a multitude of distant but bright star-like light-sources inexplicably luminesced, revealing the amorphous earthen globs to the video feed. Upon close examination, a blue glow resembling the previously observed anomalies was visible an indeterminable distance away, though significantly brighter than when it had been previously encountered. Two separate researchers reported mild discomfort after attempting to more closely examine the image.

Approximately three minutes later, the glow and "stars" intensified further along with the radiation. Shortly thereafter, readings from all of the explorer's instruments became completely erratic with no discernible pattern, including the video feed, in a similar manner to the anomalies recorded in Experiment Log 1123-IV. After approximately thirty minutes, the readings changed again, but were still indecipherable except the video feed, which appeared to depict incredibly large bovine-like creatures in place of the "land-masses" that had previously been observed. Researchers attempting to pan the camera downwards discovered that it seemed to move in random directions, even when a constant signal was given. Once a satisfactory angle was attained, it was confirmed that the Explorer appeared to be resting a similar bovine mass. After approximately twenty minutes attempting and failing to take a sample of the "hair," readings shifted once more. Initially appearing nonsensical, the researchers present were quickly able to work out that there were seemingly consistent "gaps" in the data and were able to, through a combined effort, come to the conclusion that the electromagnetic waves being received by the Explorer were in fact constant positive signals interspersed with discrete absences of energy rather than actual photons. The data was recorded and set aside for later analysis, as shortly after this discovery was made there was another shift.

After several tests and checks were completed, it was determined that all readings were completely normal, and that a position was being transmitted from SCP-████. Readings from SCP-████ indicated that the Explorer was located extremely far away, located [REDACTED], though the validity of this data was questioned. Before more information could be gathered, an alert triggered by excessive radiation drew attention to the video feed. The "stars" were observed to become increasingly brighter, and the blue glow appeared to be moving towards the camera very slowly. The radiation seemed to be growing exponentially, and the Explorer's operators expressed fears that the radiation may soon cause the robot to break down as the video feed showed the landmasses beginning to crumble, presumably from the more radioactive elements composing them breaking down. This presumption was supported by the increasing readings of other types of radiation received from the Explorer. Researchers made the decision to remain and observe the phenomenon as it was possibly an important component of SCP-1123-2's behavior. Little else was observed, however, as the masses continued to disintegrate and the video feed degraded over the course of the next twenty four minutes. Once data ceased to be received from the Explorer, the expedition was declared complete and documentation procedures began.

Approximately one minute and fifty five seconds after the Explorer's signal discontinued, all researchers present spontaneously and with an inexplicable simultaneity halted their actions and turned their attention to the video feed, which now displayed a faded image of the blue glow observed previously. Notably, the characteristic pair of dots were now roughly twice the size relative to the total shape and alternated between black and white. At this point, all video and audio recordings of the test chamber began to malfunction. What follows is based on the testimony of Dr. █████, who had already vacated the testing room.

An estimated ninety three minutes following the recording malfunctions, Dr. █████ returned to the test chamber in order to retrieve the experiment logs. Upon his entry, he saw what he described as a sea urchin-like construct crawling on the floor. Dr. █████ immediately signaled security and began to evacuate the room before he realized that the "sea urchin" was, in fact, a mass of his researchers with their limbs interlocked in strange ways. The doctor found his gaze inextricably drawn to the video feed where the blue glow remained. He described the feeling that the glow could somehow see him and found himself unable to move for several moments. The words "You have been inside me, and now I have been inside you." reportedly echoed inside of his head, accompanied by images of [REDACTED] on a planetary scale.

This continued for approximately ten seconds before SCP-1123 began to scream emphatically. The blue glow dissipated almost immediately after Dr. █████ perceives a large grin, and the instance of SCP-1123-1 closes. At this point, video and audio recordings are restored. The group of researchers appear lying on the floor in a pile. SCP-1123 ceases screaming and begins to vocalize.

SCP-1123: Psychological attacks characteristic of Entity detected. This beacon will take immediate string-disorienting action. Take caution.

Dr. █████: What does this mean?

SCP-1123: Mistakes.

Dr. █████: What mistakes did we make?

SCP-1123: PROGRAMMED RESPONSE: We sincerely hope you are not the last sapient life to have not been devoured.

SCP-1123 became unresponsive despite further attempts to question it by Dr. █████ and the arriving security team. Its radiation began to increase slowly and it began to float. Efforts were made to contain and monitor the changes in SCP-1123.

Addendum: Both the researchers and Dr. █████ underwent thorough physical and psychiatric evaluations, but no significant trauma was found. The researchers reported severe muscle and joint stiffness for the following weeks, as well as mild cases of scopophobia. Dr. █████ stated that the "grin" he supposedly saw on the blue glow occasionally superimposes itself over the faces of those he converses with, but that he can overcome the resulting discomfort with some effort. Following this incident, Dr. █████ has made every effort to have SCP-1123 upgraded to Keter classification.
